most guys are going with lightweight wheels like the Sparcos, I took out my rear seat bottoms in my 12' Hatch, It was most so that I had more room to move my seat back when I had seats down, but thats few pounds. The Steeda Lowering Springs I swapped were lighter then stock springs but Im not sure how much. The Steeda Sway bars are also half the wieght of stock as well. Most Aftermarkey exhaust are lighter as well.
